<i>I have read that Wx is faster than Tk</i> <p>
I'm not sure where you heard that, or what sort of application they were talking about. <p>If you want a filehandle watcher in Gtk2, you can do that, Gtk2 is pretty good in my book, although I never had trouble with Tk's speed, unless the number of widgets were very large.
<p>You can run mixed event loops by making one loop a master, and the other a slave. The slave loop gets pumped every so many milliseconds by a timer in the master loop. See [id://870108] and here below is a Gtk2-Tk hybrid script. It may be useful.
<c>
#!/usr/bin/perl -w
use strict;
use Gtk2;
use Tk;
#setup Tk loop
my $mw = MainWindow->new(-title=>'Tk Window');
my $count_tk = 0;
my $labtk = $mw->Label(-textvariable =>\$count_tk)->pack;
#setup Gtk2 loop
Gtk2->init;
my $count_gtk = 0;
my $window = Gtk2::Window->new('toplevel');
$window->set_title('Gtk2 Window');
my $glabel = Gtk2::Label->new("This is a Gtk2 Label $count_gtk");
$window->add($glabel);
$window->show_all;
# make Tk loop the master, but you could make Gtk2 master if desired
# the lower the repeat rate, i.e. 1 ms,
# will give more cpu time to the gtk2 loop
# this is sometimes called manually pumping the event loop
my $tktimer = $mw->repeat(10, sub{
$count_gtk++;
$glabel->set_text("This is a Gtk2 Label $count_gtk");
Gtk2->main_iteration while Gtk2->events_pending;
$count_tk++;
});
$mw->Button(-text=>' Tk control Quit ',
-command => sub{exit}
)->pack();
MainLoop;
